Answer:
x = 10
y = 15
Step-by-step explanation:
Angles 8x - 10 and 7x are congruent because they are alternate interior angles of parallel lines cut by a transversal.
8x - 10 = 7x
x = 10
7x = 7(10) = 70
6y + 20 and 7x are supplementary since they are a linear pair.
6y + 20 + 7x = 180
6y + 20 + 70 = 180
6y = 90
y = 15
Answer:
2/0.74
Step-by-step explanation:
To solve the polynomial, factorize it.
2x³-11x²+18x-8=0
After factorizing:
(x-2)(2x^2 - 7x +4) = 0
now, solve each bracket one by one:
x-2 = 0
x = 2
Then
2x^2 - 7x + 4 = 0
use quadratic formula t get 0.74
The answer is 16 because 16•5=80 and then 80-9=71 yk?
10 km in .5 hour. Since it is the same as 20 km in 1 hour. Multiplied by 2.
20 is greater than 15.
